Modulus in Stage construction - Hardening Modelling

Paula Viertel — Thu, 16 Sep 2021 14:18:52 GMT

I don't know if I did well my model using HS model.

In my case the model is related with a dam construction. I used 11 stages.

When I verified the modules adopted by Plaxis, I discovered Plaxis used Eur in place of E50. ¿Is that correct?

I thought the correct way to solve the problem is considering E50 when you put a new layer because you load for first time this layer. Please let me know if I analyze in a good way this problem.

The following pictures shows 1. Soil Properties, 2. The section where I reviewed modulus, 3. Graph including: Current Young Modulus (Extracted from Plaxis), Theoretical E50 modulus, Theoretical Eur modulus.

Troubles with an apparent divergence point

Hello:

I tried to do a consolidation analysis using Soft Soil model after of an undrained analysis (with excess of pore pressure), but when I reach certain construction stage, one point shows a great value of positive displacement (the point fly literally).

The point is in the border of two materials (is a corner), one of these materials is modeled with mohr coulomb (the purple) and the other is modeled with Soft Soil (the yellow). I tested doing the mesh more fine in this zone, but this not solved the situation. I don't know what happened. Please let me know if I have to do other thing in the model.
